Abstract: Methods and apparatus for improving emergency wash systems for compact, low flow emergency eyewash systems that provide tepid water at low flow rates and systems that are adapted and configured to reduce the exposure of users to Legionnaire's Disease with washing system features that permit quick, efficient, high flow rate flushing of the plumbing providing water to the washing system. Still further systems provide tepid water from a thermostatically controlled mixing valve that has a multi-function body.

Abstract: Apparatus and method for providing tempered water to an emergency wash system. Various embodiments include simple, reliable, low-cost flow regulators to reliably provide adequate emergency wash flows. Yet other embodiments include one or more features that consider the special needs of a person temporarily blinded, and include those persons having disabilities.

Abstract: Apparatus and methods for providing fluid such as water at a controlled temperature. In some embodiments, hot and cold fluid is provided to a thermostatically controlled mixing valve, which then provides fluid at a mixed temperature to a plumbing system. The thermostat provides a first loop for closed-loop control of fluid exit temperature, and preferably there is a second, electronically controlled closed loop for adjusting the temperature of fluid exiting the valve. In yet other embodiments the electronic control loop is fail-fixed, such that a loss of electrical communication to the actuator results in the actuator maintaining its last position. In yet other embodiments there is a system including a flow sensor and a recirculation pump such that the temperature of the fluid exiting the valve cannot be adjusted if there is insufficient flow, or if the pump is actuated.

Abstract: Methods and apparatus for washing systems, both industrial and residential. Some embodiments pertain to face washing systems that provide a gentle upward flow of water for washing a person's face, but which can be easily reconfigured to provide a downward flow of aerated water for washing of the user's hands. Other embodiments pertain to visual indicators to help a user in a dark environment in the use of an emergency eyewash system. Yet other embodiments pertain to eyewashing systems incorporating filters that are automatically flushed of debris. Still further embodiments pertain to emergency eyewashing systems in which a mixing chamber is located downstream of a thermostatically controlled valve to reduce the possibility of a hot temperature spike being provided to the eyewashing outlet apertures, which could be harmful to users.

Abstract: Mixing valve turbulence generators and methods are disclosed. Embodiments include turbulence generation apparatuses and methods that increase the turbulence of, impart swirl to, reverse the direction of, create tortuous paths for, and/or accelerate the mixing of hot and cold fluid within a valve assembly. Alternate embodiments include angled radial slots, angled surfaces and fin-like baffles to enhance the mixing of hot and cold fluids.

Abstract: Apparatus and methods for integrated emergency wash systems. Various embodiments pertain to integrated shower and eyewash emergency wash systems, including those that are particularly space efficient. Other embodiments pertain to emergency shower nozzles that provide sprayed water in sheets, especially a cylindrical sheet that generally describes the perimeter of the shower spray area, providing the user a significantly quicker removal of contaminant material during a shower. Still further embodiments pertain to improved flushing systems, especially flushing systems adapted for the space efficient, low flow integrated systems described herein.
